Although the movie rights to The Last Algonquin have been sold, a movie based on the book has not yet been made.

Theodore Kroeber's Ishi: Last of His Tribe (1964) is the true story of Ishi, the last known member of the Yahi tribe of the Lassen area of northern California.

His story is similar to Two Trees's in that he was truly the last of his band.

His life also differs from Two Trees's in that while Two Trees stayed out on his own and had his last human contact on his own turf with a twelveyear-old white boy, Ishi ended up as a subject for study of anthropologists at the University of California, San Francisco. As a result, we have photographs of and other information about Ishi; there is no such independent corroboration of Two Trees's story.
